Incomplete combustion

What causes incomplete combustion?

 * Insufficient air supply to the flame.
 * Insufficient mixing of air and fuel.
 * Insufficient time to burn.
 * Cooling of the flame temperature before combustion is complete.

What is formed in incomplete combustion?

 * Carbon monoxide is usually formed in incomplete combustion

Incomplete combustion reaction equation: hydrocarbon + oxygen → carbon monoxide + carbon + water Carbon is released in this reaction, forming soot. The reason why complete combustion is preferred is because carbon monoxide is considered as a poisonous gas.

Problems associated with incomplete combustion.

 * Environmental problems :

These oxides combine with water and oxygen in the atmosphere, creating nitric acid and sulfuric acids, which return to Earth's surface as acid deposition, or "acid rain." Acid deposition harms aquatic organisms and kills trees. Because it makes certain nutrients, such as calcium and phosphorus, less available to plants, it reduces the productivity of ecosystems and farms. An additional problem associated with nitrogen oxides is that they, along with hydrocarbon pollutants, contribute to the formation of tropospheric ozone, a major component of smog.


 * Human health problems :

Breathing CO can cause headache, dizziness, vomiting, and nausea. If CO levels are high enough, you may become unconscious or die. Exposure to moderate and high levels of CO over long periods of time has also been linked with increased risk of heart disease. People who survive severe CO poisoning may suffer long-term health problems.
